This invention relates to improvement in-` injecting devices and more articularly to devices speciall constructed or injecting or harmful effects produced by nicotine.

The invention has for its primary object to provide a simple and effective device for into the mouth of the smoker during smoking.

. deposits afpredetermined and uniform quan-- A further object of'thev invention is the provision' of a. device for injecting liquid.

into tobacco articles which, at each operation,

tity of the liquid, thereby avoiding undue wetting ofthe tobacco, the quantit of liquid discharged from the device, 'owever, being sicient to impregnate a zone within the cigarette and prevent passage of the poisonous fumes.

A further object of the invention is the provision of an injecting device-Which includes means -for preventing the obstruction of 'therdischar e orifice for the liquid.

A further o ject is the provision of an injectin device. including a .container in which t e liquid may, be safely stored for long periods without danger of deteriorai tion.,or leaka e.

With the oregoing andother objects in view' theinvention consists in the' various structuralfeatures to be hereinafter more fully described by reference to the vaccompanying drawing, in` which the figureis a Alongitudinal section of an injecting, device constructed in accordance with the invention.

. Referring to the drawing in detail,`the numeral 1 indicates'a cylindrical container which is open at oneend to permit of the V'ofy a cigarette or like tobacco article. Thev convenient introduction of the liquid and is provided at its opposite end with a restricted passage ',commumcating with 'a tubular member 2 which latter i-s bevelled' at its outer extremity to provide a penetrating point for convenience of its insertion in the terminal tubular injecting member 2 is of such length that when it vis introduced into the end of Ation sholild be .depositing special liquids in cigarettes, cigars and tobaccos, such liquids acting to avoid the a cigarette, for instance, it terminates `within the latter at a (point where theliquid solueposited.

The bore of the injecting member 2 in i' l line with the axis of the hollow container 1 and a cleaning rod 3 provided with a point! v ed terminal lying within the member 2 ex tends throughout the entire length of the latter as well as the container 1. The cleaning rod 3 -is of less diameter thanthe interior of thetubular member 2 so as' to permit of the free passageof liquid from the open terminal of the member 2,` as during the injection of ,a quantity of liquid into a' cigarette.

The cleaning rod 3 is connected at its end opposite the member 2 with an actuating but ton 4 which is located externally of the con; tainer 1 and-provided-with a flange 5. A cap 6 is removably threaded on the open end of the container l and is provided with an opening through which the push button 1 projects so that the latter is exposed and is conveniently accessible to the user. The ange 5 confines the button 4 in position and Vprevents the latter from being withl75 f drawn -from the cap. A rubber disc or dia.- phragm 8A is confined between the open end of the container- 1 and the ange' and normally retains the latter in the outwardly proi 39.

j ected position illustrated. The cleaning rod is of such length that, ywith the button 4 eo 'l in the normal position shown in the drawing, the pointed extremity of therod lies just dinside of'the open end of the tubular injectin -member 2 sc that upon depressionof the utton 14 the rod 13 is forced outwardly, thereby clearing the bore of the ini v charge ofliqui from the container-1 is prevented by a second cap 9 which is threaded yon the end of the container 1 and is provided with a hollow rubber plug 10 snugly receiv-A ing the projecting member and closing the 'i open end of the latter. In order to prevent loss of the cap 9 the latter' is preferably connected with the container l by means of a chain or other flexible article indicated in dotted lines at l1 in the drawing. W hen the container is filled with the liquid solution the cap 6, button 4 and rod 3 are replaced and the injecting device is in condition for use.

Only a single drop of liquid passes out of the injecting member 2 at each actuation or depression of the push button 4 and cleaning rod 3. rlhe quantity constituting each drop depends not only upon the viscosity and the cohesion of the liquid in the vesselas well as on the degree of pressure exerted by the compressed disc 8, but also on the clearance space provided between the cleaning rod 3 and the interior of the injecting member 2. Upon depression of the vbutton d the thin liquid annulus present in the nova7 annular's ace between the rod 3 and the inner wall o the member 2 is pulled forward and leaves the member 2 in the form of a drop. It will be understood that the rubber disc or diaphragm 8 acts to restore the push button fr to initial position following a depression thereof and when compressed tends to exert a pressure on the body of liquid contained in the container l assisting in the injection or a drop of liquid from the open end of the member 2. However, the displacement ofthe diaphragm or disc is so sli ht as toeectively restrict the quantity of iquid ejected or discharged to a single drop, thereby avoiding the discharge of an undue quantity of liquid into the cigarette or like tobacco article and ensure the discharge of uniform quantities oi liquid at each operation.

Due to the provision of the cleaning rod 8 and the connection of the latter with the button 4 it is moved axially through the interior of the ejecting member 2 at each depression o the button 4f and effectively clears out any particle of tobacco which may enter the member 2 and tend to obstruct the passage for the dischar e ofthe liquid. The device possesses the urther advanta e that drops of liquid may be dispensed wit equal facility and accuracy irrespective of the quantity of liquid in the container.

The device is preferably constructed of material which is acid-proof and the inside of the container is preferably covered with tin, chrome or the like, while the cleaning rod may be constructed of non-corrosive steel.

What I claim is:

1. In combination, a hollow container having one end open, an injecting member at the opposite end ofthe container having a discharge opening therein, a rod extending through the discharge opening of the injection member, and a button carried by said rod and projecting from the open end of the container. Y Y Y 2. In combination, a hollow container having oneen-d open, an injecting member `at the opposite end of the container having a dier charge opening therein, a lrod extending through the discharge opening of the injection member, and a button carried by said rod and projecting from the open end of the container, said rod having a pointed end movable through the injecting member.

3. In combination, a hollow container having one end open, an injecting member at the opposite end of the container having a discharge opening therein, a rod extending through the discharge opening of the injection member, a button carried by said rod and projecting from the open end of the container, and a compressible seating member interposed between the open end of the container and said button.

4. In combination, a hollow container having one end open, an injecting member at the opposite end of the container having a discharge opening therein, and a rod extending through the discharge opening of the injection member, said injecting member and rod having pointed ends.

5. In combination, a hollow container having one end open, an injecting member at the o posite end of the container having a disc arge opening therein, and a rod extending through the discharge opening of the injection member, said injecting member and rod having pointed ends and said rod extending substantially throughout the entire length of discharge opening ot the injecting member.

6. In combination, a hollow container having one end open, an injecting member at the opposite end of the container having a disc arge opening therein, a rod extending through the discharge opening of the injection member, said rod extending substantially 'throughout the entire length of the container and of the discharge opening of the injecting member, and a button located at the open end of the container and connected with the rod for displacing and causing the latter to project from the open end of the injectinlg member.

7. n combination, a hollow container having one end open, an injecting member at the opposite end of the container having a discharge opening therein, a rod extending through the discharge opening of the injection member, a button carried by said rod and projecting from the open end of the contamer, and cap members applied to the opposite ends of the container, one of said cap- Alike members confining the button and the other cap-like member closing the injecting member.

In testimony whereof I aiix my signature.
